From where should the musaafir calculate the 77 km distance required for a valid Shari' journey?

Answer

The safar (journey) distance should be calculated from the end of the town/city where the built-up area ends, from whichever side one leaves the town/city. If there is no end of the built-up area, that is, the buildings encroach on even the next town, then calculate the distance from the official boundary of the town/city. The distance is never calculated from one's house. The boundary refers to the boundary of the town/city, not the municipal boundary.
